How Type ALT Works

The Alfa Laval ALT is a Top Mounted Agitator, offering mixing solutions to meet a wide range of requirements in Food, Dairy, Beverage, Distilling, Pharmaceutical, Biotechnology or Personal Care applications. 

The ALT Agitator has an electrical drive motor that either directly or via a gearbox, rotates the Agitator shaft and EnSaFoil Impeller(s). This unique impeller design and highly effective axial pumping effect minimise shear forces on the product, and ensure the product is treated gently, resulting in highly effective mixing and blending of the entire tank contents.

Duties Typical Examples
Maintaining mixture homogeneity Milk storage tanks, cream tanks, mixed product tanks, UHT, and product storage tanks
Mixing suspensions and solutions Fluid and fluid mixing, drinking yoghurt and fruit mix tanks, flavoured milk mix tanks, and syrup mix tanks
Dispersing Powder protein and oil mix tanks, micro salt and milk product mix tanks
Suspension Fluids with particles, juice tanks, crystallizing tanks, etc.
Heat transmission Circulation of media in tank with dimple jacket (cooling or heating)
Flocculation Wastewater treatment tanks
Operation features Due to
Low energy consumption The wide range of high efficiency propellers and drive units makes it possible to design for low operational costs
Gentle product treatment The wide range of high efficiency propellers makes it possible to design for low shear operation
Hygienic features Due to
Easy external cleaning Stainless steel bearing frame design with seal O-rings (for washing)
Connections inside the tank (risk zones) can be minimised Bearing frame drives with drive shaft and special internal shaft connection without having a flange coupling inside the tank
Good drip off properties No plane surfaces or grooves on internal parts
Easy CIP No interior shadow sides between the blades and smooth surfaces
Maintenance features Due to
All servicing (replacement of wearing parts such as shaft seals, bearings, etc.) can be done from outside the tank Bearing frame drives with detachable shaft which can be dismounted from outside the tank
Easy dismantling Use of spider type coupling and stainless steel parts
